R576 and The River Feale.

In which direction is the River Feale flowing? Is the local mountain range, Mullach a'Radharc latitudinal or longitudinal? Why so? By extension are the Kerry/Cork mountain ranges latitudinal or longitudinal?
Why is the R576 running parallel with The River Feale? Measure the length of the River Feale from source to sea as the crow flies. Compare your result with its official length. Note the flowing directions of the tributaries.
